To start MySQL as service, please run “C:\Program Files\MySQL\xampp\mysql_installservice.bat” ( using the “MySQL Console Panel” does not really work, somehow ).

XAMPP 1.7.3 is the latest version for W2k.

XAMPP 1.7.4 ( ( “VC6” is part of the names of archives and installer ) and XAMP 1.7.5 and newer ( “VC9” ist is part of the names of archives and installer ) are shipped with a version of MySQL which is compiled so that it just runs on WinXP, but not on W2k anymore .

XAMPP 1.7.7 is the latest version shipped with PHP5.3.

XAMPP 1.8.1 is the latest version for Win7 with “Pentium III” CPU. It is shipped with PHP5.4. By default,it causes much warning messages with “standard” PHP5 code running bravefully on PHP5.3, e.g. old editions of DokuWiki.

XAMPP 1.8.2.0, 5.5, 5.6 & 7 and newer require a “Pentium IV” CPU.

Warning:

Apache server of XAMPP is using both port 443 and a configurable port ( by default, port 80 ).

According to experts, Drupal 5, 6, 7, 8 are totally incompatible . These experts suggest to setup a new project with empty codebase, when moving from one version ( 5, 6, 7... ) to the next ( 6, 7, 8,.. ) .

TENCompetence Foundation "Liferay Portlets" - “Test Portlet. The Test Portlet allows users to take tests in order to self assess aspects that are relevant in setting realistic goals, like aptitude, motivation, personality, learning style, etc.. These tests are created using the QTI Editor Portlet”.

It might be interesting to develop a Moodle Portlet . Be aware that you then you need to develop an additional single-signin solution.

According to reliable users, you may open, close and reopen an account with same username and same E-Mail address .

Other social network communities, which might be entitled “Social Media-Sharing Communities”, allow the users to browse the uploaded media contents ( photos and videos ). There is no central place at WoWonder for that.

The photo and video contents is hidden on the profile walls and albums of the users. This might be ok for a true social community with mostly private photo and video contents ( e.g. Facebook ), but is a fault in case of a photo and video community, where sharing of media contents is of major interest both of the uploaders and the consuming users.

Message system.

There is no true message system, but just a chat system. The chat system has a limited buffer, so that chat contents is not saved permanently.

The chat system looks like to Facebook chat, with a user interface at left bottom of the browser window. But in opposite, at Facebook, all messages are saved.

If you press the button “Delete Messages”, maybe all messages are deleted for both chat partners!

There is one message buffer URL for the sender, and another buffer URL for the receiver. So a complete message communication channel consists of 2 message communications URLs.

If you bann another user

The message buffer is also officially unavailable for this user, i.e. the banned user can´t read the old messages anymore .

But if you get banned by a friend, you will be informed about his / hier birtday, at the WoWonder community start page .

How to get the access to the message buffer again:

You still must know the URL of the user. The URL username must be not identical to the screen name.

Open another ( free ) account, best by another Internet browser.

Just if writing of messages is enabled by default, for users who are not friends, you may access the old messages of your first account. Else not!

Open the chat message window.

Change from chat message window to full message buffer page. Copy the URL.

Login with your old account.

Paste the URL of the full message buffer page.

Just in case that the message buffer page doesn´t load, load the message buffer page of another no-blocked account, change the message buffer number to the wanted message buffer, and load again. A wonder, by wonder, ususually this works to load the requested message buffer page.

You might even write messages to the account, who “blocked” watching the profile page.

“Search / Advanced Search”: Software bug, as of 2018-03: The given search criteria ( e.g. “country = Germany” ) are ignored for further results, if you press “Load more users”

“Forum / Members”: Software bug, as of 2018-03: The given selection criteria ( e.g. “All members with username which starts with 'A'” ) are ignored for further results, if you press “Load more users”

There is no image preview with limited image size. If an image, e.g. 1 MByte of size, is visible on a Wowonder profile page, it is loaded completely.

The number of curently logged in users is displayed at the bottom of the front page, right side, e.g. “Online Users 63”.

WARNING: I found an implementation of WoWonder, where multiple videos are downloading as soon as you enter the website, automatically, though you don´t run a video. E.g. if you stay 10 minutes on a single page, it might have downloaded all videos completely. This might ruin your Internet high-speed data volume, if you have an Internet volume data tariff ( e.g. 2 GB/month ). According to a WoWonder user, there is no easy configuration to deactivate preloading of videos...

As experienced, uploaded media is not protected from external access. I.e. if you pass a link to a media object, people without cms account may view or play the media. Videos and pictures are stored with hash names, e.g. with “xxxxx” as placeholder for a hash value

If you put a link to a YouTube video into a ZB wall message, this is even mentioned at the top of the message, next to your user name “Youtube”. The video is embedded into the message and can be played. But the link to such included YouTube videos can´t be edited. If you edit a message which includes a YouTube video link, you may edit the other text, other URLs in the message, but not the video URL.

User feedback in 2018-03:

Dear admin of a WoWonder community, you may reduce your bandwidth charges by not allowing it to queue more than one stream at a time. I noticed it downloading 5 at once on a page where i was not going to watch any of them

User feedback in 2018-02:

I started with normal small server, about 130$/month, but the user experience even with a small number of users was, that “WoWonder” was so slow.

So I decided to upgrade. I upgrade several many times until this server, but still need more bigger.

Now we have more than 100 concurrent users, at best times.

The number of messages is enourmous. E.g. this month, in the first 3 days.... total number of messages is more than 2 millions ( 2.111.305 ). I.e. about 700.000 messages / day.

The traffic is not the problem. problem are ram, cpu. The server need 256 GB RAM but this is too much expensive.

By looking at the current upload statistics: Images can upload 10 in 5 minutes. And videos more than 20 in 1 hour. So the number of currently active users is less important for the RAM consumption.

Also our database is so big.

User behaviour and system behaviour analysis:

Estimated 5% of the active users are active frequent uploaders of photos and videos, especially they “send” messages with photos to other users, by posting messages on the other users' profile walls.

Especially, the uploaders are “collectors of 3rd-party videos and photos”. So they upload mostly 3rd-party stock video and photo contents, not own contents. It would be very hard and in most cases impossible for most active uploaders to generate own contents in that bulk masses.

So estimated 5% of the active users ( i.e. less than 1% of the registered users ) cause the demand for an expensive server with enormous amount of RAM and CPU power for processing the video and photo uploads ( and playing the videos by a broad number of users )

Additionaly, there might be a fatal software misconfiguration: If a user enters a user profile page, photos published on the profile's wall are loaded and especially videos ( not just one, e.g. up to 5 if 5 are on the page ) are preloaded by concurrent background download even if never played.

A: “It depends on the process that you’re executing, not all the processes kill 2MB of ram, there may be a loop that takes 500MB, and there may be a MySQL query that takes 1 KB of ram. I agree that it’s so recommend to use Node.js, but again, it’s not available in shared hosting, so we’ll lose the customers that are using shared hosting”.

“I can increase the RAM & Disk space of the server, in future upto 512 GB & 50 TB. You have mentioned the script can handle 1 million user. How much user the script can handle at maximum level if i increase the server? Is there any limitation”.

A:

“1. Unlimted even if you are on a shared hosting. (just data)”

“2. Can handle as much as you want, but it will depend on your server, for example on shared, just 5 till 10 online users or chatting, on VPS 2GB ram 50+”.

“3. Your server is just perfect, it can handle 1000+ online/chatting users easily”.

“4. There is no limitation, but once you reach 1M, you gonna have to stop using one server and start using multi servers or cloud hosting and a team to manage those and separate the script databases etc.”

Oxwall is a “plugin hell”, means almost anything and everyting may be achieved by a plugin and must not be integrated in the kernel. On the other hand, by this a rich commercial marketplace for payware plugins was created...

I was told by experts, that mobile Oxwall solutions may be created by commercial plugins and commercial smartphone apps...

I was warned by experts, that the Oxwall code owners are sort of “arrogant” as typical for Nerds, in the means that there is no positive and working process for reporting bugs, to get reported bugs accepted as bugs ( instead “it's just your server where our Oxwall contact formular code is reported to fail, so it must be your fault and not that of the Oxwall code...” ), and then the bugs fixed....

“There is a reason why there are no free scripts listed in this article: They all suck. I checked out dozens of free scripts. Their designs were poor and they had not been updated in years.

“Sadly, Etano Community Builder Script ( formerly: DateMill ) is the best of a bad bunch; however I wanted to ensure there was at least on option for those of you on a budget. In my opinion, you would be better using the free script BuddyPress instead of this”.
